FASTENING DEVICE.

' Application mea May s,

To all whom it may concern:

Be it known .that I,.Loms A.\.LUP1EN, a citizen of the United States, residinor at Brooklyn, in the. coun-tyof Kings andA gtate of New York, have inventedy certainnew and useful Improvements inv Fastening. Devices, of which the following is a specification..

This invention relates. to an adjustabl clasp or fastener,construction.

A general object ofthe invention. is to provide a fastener ofj the general Vnature referred to in. which adjustments can Kbereadily made and which willfsecurelyhold the parts in the relative positions inwhich vthey are placed` in` anadjusting operation.

The. invention includefsfxa keeper; member in the formof a strip of sheet material `provided.y withsuitable perforations, anda locking member having two off-set. flat portions adapted to take positions, one in front of and the other at the rearward face of the keeper, the keeperv passing throughfa slot That por.-.

intermediatethe flat. portions. tion of the locking member'at therear of the keeper is provided with-a forwardly extend-v ing lug for engagementwith the vperforations in the keeper. .In one rform of the invention the lockingmember ,also` is pro- ,videdv with lugswhich extend rearwardly to engage with perforations in Vthe keeper,

Other featuresfof the invention willbe hereinafter. described.

In the drawings, inwhich a preferred embodiment of the invention has beenl selected for illustration,y

tailed description of the invention, in Figure 1 the two terminal membersl() and 11 of a belt or band are provided respectively with a keeper plate 12 and a locking member 13 for .fastening cooperation with thekeeper member 12. f v Y The keeper 12 preferably takes the form of a thin elongated strip of'sheet metal or other suitable `material riveted at one end as at 14 to the band 10 and extending along the `the flat portion lf3-being attached to the forwardface of the bandy terminal 11 and bent rearwardly across the end of the band section. 11 as at-18 tol connect the forward flat portion 16.with: the rearward flat portion 17 which -i-,nruse lies. against the rear surface of` the keeper member 12 and. forwardl vof the adjacent terminal portion 10 of the band or strip. The connecting portion 18 .between "the fla-tbody portions -16 and 17 of the locking. member 13 is provided with a slot 19,1

fthroughwhich the vkeeper member 12 eX- tends as is clearly shownv in Figures 1 and 2 of the drawing, the keeper thus extending long the rear surfaceof the terminal. mem

In orderto interengage the locking member. 13 with the keeper 12 the rearward flat body portion v17 of the locking member is provided with an outwardly or forwardly extending lugmember. 2O which has the general conformation of. the transverse slots or seats 15in the keeper vand which is adapted to be placed in one ofthe slots to thereby lock the parts in relatively immovable relation to each other. The interengaged position of the parts is shown in Figures 1, 2 and 3 of the drawing and it will be seen that when the parts are in their mutually engaged position the locking member 13 lies in a comparatively flat position with relation to the keeper with which it 'is interlocked, this position of the parts serving to securely maintain the interlocked condition thereof.

In Figures 4 and 5 of the drawing the forward flat portion 16 .of the locking mem- Cil ber 18 is provided with a pair of rearwardly extending lug members 21 which cooperate with the lug 2'() on the rearward portion 17 to provide a doubly secure locking relation of the parts. ln order to make use of the locking lugs 21 on the forward portion 16 of the locking member the keeper 12 is provided with an additional set of openings 22, as is clearly shown in Figure 7 of the drawing, into which the rearwardly extending lugs 2l project in the locked condition of the parts as is shown in Figure 6 of the drawing. lt will thus be seen that a doubly ffectire locking engagement of the lool-,ring member 13 and the keeper 12 is effected by the construction shown in Figures et to T of the drawing.

ln either form of the invention described the operation of adjusting the parts to a new position is readily accomplished by tilting or turning the locking member 13 outwardly so as to disengage the rearwardly extending lugs 21 from their engagementl with the keeper 12 and also to disengage the forwardly extending lug 2O from its position in one of the slots 15, the keeper turning for this operation about the rearward edge Q3 of the rear portion 17 as a fulcrum. The 0perat-ion of moving the locking lugs into engagement with a different set of openings can then be readily accomplished whereupon the parts are restored to their relatively. flat and parallel positions in which the locking engagement of the parts is securely maintained until a further adjustment thereof is deliberately made.

lVhat I claim is:-

1. ln an adjustable fastener, a keeper hath ing the formation of an elongated strip with spaced apart seats, a locking member including two substantially parallel mutually offset and oppositely extending flat members arranged to lie one in front and the other at the rear of the keeper, a connection between said tiat members extending substantially at right angles thereto and provided with a slot through which the keeper may extend a forwardl f extendine' lu@ on the .5 b h rearmost flat member having locking engagement with a seat in the keeper and a rearwardly extending lug on the other flat member for engaging another seat in the keeper.

2. ln an adjustable fastener, a keeper having the formation of an elongated strip with spaced apart seats, a looking member including two substantially parallel mutually ofl set and oppositely extending flat members arranged to lie one in front and the other at the rear of the keeper, a connection between. said flat members extending substantially at right angles thereto and provided with a slot through which the keeper may extesid, an angularly extending lug on one of said flat members for locking engagement with a seat in the keeper and oppositely extending' angularly projecting lugs struck from the edge portions of the other flat' member for engagement with other seats in the keeper.

8. In an adjustable fastener, a keeper having the formation of an elongated strip with spaced apart seats, a locking member ineluding two substantially parallel mutually offset and oppositely extending flat members arranged to lie one in frontvand the other at the rear ofthe keeper, substantially parallel with said keeper and with the member at the rear in flat engagement with the back of the keeper, a connection between said [iat members extending substantially at right angles thereto and provided ,Y

with a narrow slot through which the keeper may extend and a forwardly extending lug on .the end of the rearmost fiat member for lockingvengagement with the seats in the keeper. c

et. ln an adjustable fastener, a keeper having the formation of an elongated strip with spaced apart openings therein, a locking member including two substantially parallel mutually offset and oppositely extending flat members arranged to lie one in front and the other at the rear of the keeper, a connection between said flat members extendin substantially at right angles thereto and provided with a slot through which the keeper may extend, a forwardly extending lug on the rearmost iat member having lockii'ig engagement with an opening in the keeper, and a rearwardly extending lug on n the other flat member for engaging an open- Loms A.
